We study friction and vibration, which are inevitably generated when machines are operated. In particular, we focus on sliding bearings and non-contact seals, which are the mechanical elements that make up rotating machines. The dynamic characteristics of these mechanical elements are elucidated through experiments and numerical analysis, and are used to solve problems that arise in actual machines.
